一. 页面JSP代码如下
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8" %>
<pre name="code" class="html"><%
String userName = (String)request.getAttribute("username");
%>
<html>
<head>
<title></title>
<meta http-equiv="content-type" content="text/html; charset=utf-8" />
<script type="text/javascript">
//{1} 定义主框架头panel
var headPanel = new Ext.Panel({

});
//退出系统
function logoutclick(){
Ext.Msg.confirm("警告","是否退出系统？",function re(o){
if('yes'==o){

}
//{2} 定义主框架功能菜单panel
var menuPanel = new Ext.Panel({

var viewport = new Ext.Viewport({

//增加一个TAB，存在则直接显示

</script>
</head>
<body scroll="no">
<div id="headPanel">
<table width="100%" height="36" border="0" cellpadding="0" cellspacing="0" background="images/top-bg2.gif">
<tr>
<td width="800" background="image/control.jpg" align="right">
</td>
</tr>
</table>
</div>
<div id="menuPanel" class="x-hide-display">
</div>
<div id="pwd-win">
</body>
</html> 2.menu 数据加载
struts 配置如下:
<struts> <package name="menumanage" namespace="/menumanage" extends="sys-default"> <action name="querymenu_list" class="MenuManageAction" method="queryMenuList"> </action> </package> </struts>
java代码如下:
1.action
public String queryMenuList() throws Exception
{
Map params_new = exchangeParams();
String str = menuManageService.queryMenuList(params_new);
super.write(response, "X-JSON;charset=UTF-8", str);
return NONE;
}
2.service
public String queryMenuList(Map params) throws Exception
{
String menuStr = "";
List list = null;
if (null != params && !params.isEmpty())
{
list = menuManageDAO.queryMenuList(params);
}
return JSONArray.fromObject(list).toString();;
}
3.dao
public List queryMenuList(Map params)
{
List argsList = new ArrayList();
StringBuffer sql = new StringBuffer();
Object args[] = null;
int argTypes[] = null;
sql.append("SELECT DISTINCT M.MENU_ID ID,NAME TEXT,(CASE M.MENU_FOLDER_FLAG WHEN '2' THEN 'TRUE' ELSE 'FALSE' END ) LEAFTEMP,SORT_NO,HANDLE_REPRESENT ");
sql.append(" FROM " + this.tableSchema).append(".F_CONFIG_MENU M WHERE 1=1 ");
String userName = String.valueOf(params.get("username"));
List menuList = null;
if (!StringUtil.isEmpty(userName))
{
menuList = userDao.queryMenuListByUserName(userName);
}
String ss = "'";
for (int i = 0; i < menuList.size(); i++)
{
Map m = (Map)menuList.get(i);
String str = String.valueOf(m.get("MENUID"));
if (!StringUtil.isEmpty(str))
ss += str + "','";
}
ss = ss.substring(0, ss.length() - 2);
if (ss != "")
{
sql.append(" and M.MENU_ID in (").append(ss).append(") ");
}
if (StringUtil.isNullOrEmpty(params.get("p_menu_code")))
{
sql.append("AND (P_MENU_CODE=(SELECT MENU_ID FROM " + this.tableSchema);
sql.append(".F_CONFIG_MENU WHERE P_MENU_CODE IS NULL)) ");
}
else
{
sql.append("AND P_MENU_CODE=? ");
argsList.add(params.get("p_menu_code"));
}
sql.append("order by sort_no ");
if (argsList.size() > 0)
{
args = new Object[argsList.size()];
argTypes = new int[argsList.size()];
for (int i = 0; i < argsList.size(); i++)
{
args[i] = (Object)argsList.get(i);
argTypes[i] = Types.BIGINT;
}
}
return jdbcTemplateEx.query(sql.toString(), args, argTypes, new SuyRowMapper(MenuBean.class));
}
public List queryMenuListByUserName(String userName)
{
StringBuffer sb = new StringBuffer();
sb.append(" select m.menu_id menuid,U.* from ")
.append(this.tableSchema)
.append(".")
.append("sys_role_menu_ref m, ")
.append(this.tableSchema)
.append(".")
.append("F_config_user u where m.role_id = u.roleid ")
.append(" and u.name= ?");
return this.jdbcTemplateEx.queryForList(sb.toString(), new Object[] {userName}, new int[] {Types.VARCHAR});
}
简单表结构如下:
create table SYS_MENU ( MENU_ID NUMBER(16) not null, NAME VARCHAR2(256), TITLE VARCHAR2(256), P_MENU_CODE VARCHAR2(16), MENU_FOLDER_FLAG VARCHAR2(8), HANDLE_REPRESENT VARCHAR2(256), --PK_SYS_MENU_ID primary key (MENU_ID) ) create table SYS_ROLE_Menu_REF ( ROLE_Menu_REF_ID NUMBER(16) not null, Menu_ID NUMBER(16) not null, ROLE_ID NUMBER(16) not null, ---SYS_ACCOUNT_ROLE_REF_PK primary key (ACCOUNT_ROLE_REF_ID) )
